Particle-tuning-collision composite damper with self-adaptive damping mechanism adjusting function
The invention relates to the field of vibration control of building structures, in particular to a particle-tuning-collision composite damper with a self-adaptive damping mechanism adjusting function. Comprising a multi-particle damping unit, a base, universal rolling wheels, a composite energy dissipation supporting system and a collision plate. The multi-particle damping unit comprises a plurality of spherical particles and a cavity for containing the particles; the base comprises a bottom plate and a counter-force support; the universal rollers are positioned between the lower part of a cavity for containing particles in the multi-particle damping unit and the bottom plate; according to the composite energy dissipation supporting system, a multi-particle damping module is connected with a counter-force support, and the composite energy dissipation supporting system is formed by connecting an inertia amplifying element, a viscous damper and an axial spring in parallel. The damper can be adaptively switched among three working modes, namely a multi-particle working mode, a particle-tuning working mode and a tuning-collision working mode, and the multiple vibration reduction requirements of the structure under the action of different environments or disasters possibly suffered are met.
本发明涉及建筑结构振动控制领域，涉及具有自适应减振机制调节功能的颗粒‑调谐‑碰撞复合阻尼器。包括多颗粒阻尼单元、底座、万向滚轮、复合耗能支撑系统、碰撞板。所述多颗粒阻尼单元包含众多球形颗粒体、盛放颗粒的腔体；所述底座包含底板和反力支座；所述万向滚轮位于多颗粒阻尼单元中盛放颗粒的腔体下部与底板之间；所述复合耗能支撑系统将多颗粒阻尼模块与反力支座相连，由惯性放大元件、粘滞阻尼器、轴向弹簧三个部件并联组成。本发明使所提阻尼器能够在多颗粒、颗粒‑调谐、调谐‑碰撞三种工作模式之间进行自适应切换，满足结构在可能遭受的不同环境或灾害作用下的多重减振需求。
